I had the same issue with the seat edge, I believe that it's referred to as a waterfall edge. The rest of the chair was great, but I found that extremely uncomfortable after a few hours. Many people don't have a problem with it, however.

I also recommend Steelcase as a good alternative. I considered the Leap but eventually chose the Gesture, and am extremely satisfied.

I too had the same problem with the seat edge - and after a couple of hours it cut off circulation in my legs. Not something you want when you pay $1,300 for an office chair. I found the Mirra to be better.

The Mirra lets you adjust the tilt of the forward part of the seat, solving the biggest problem with the Aeron. It's basically an improved Aeron, in my opinion (I have both).

I got a Mirra a couple years ago, still going strong, would happily recommend it. Haven't tried the Mirra 2.

For me the Gesture is a "you never go back" chair. Once I got used to the adjustable armrests, every chair I used since felt like it was limiting my movement.
